10 most poisonous fish in the world


Most people with the word "poisonous" associate such representatives of the fauna as snakes, spiders or scorpions. Fish, as a rule, appear at the end of the listing. It is not surprising, because by virtue of the habitats of these creatures, a person may not even encounter a poisonous fish for his whole life (which is not bad, in general). However, there are brave souls who are eager to run into the dangerous representative of the marine world - in addition to their main "trump card" poisonous fish often have a very unusual appearance, which attracts additional attention to them. Deceptive beauty is not only dangerous in the habitat, some fish may pose a threat, while already in the plate. In order not to dine on the last time, you must strictly adhere to the technology of preparation of specific fish. So, for lovers of thrills, we present the ten most poisonous fish on the planet.

This striped predator, which lives near the Asian and Australian coasts, has wide fins resembling real fans - it looks really impressive. However, to enjoy the spectacle should be neat, because the zebra fish is a threat not only for "colleagues" in the ocean (motley bandit with ease can swallow a 20-centimeter fish). Blame the very gorgeous fans, in which the needles are located, filled with poison. For an untrained person, a meeting with a zebra fish can turn into a real disaster, and the hellish pain from an injection is only half the trouble. If you do not seek help in time, the poison activates and leads to paralysis of the muscles and respiratory organs, and this can already turn into death.

Katrans do not fit stereotypes about sharks. This small fish (about one meter long) will never attack a person first. Small sharks inhabit almost the entire oceanic space of the planet. But are they so harmless, and why then are they on this list? Since a person is always looking for meetings with Katrans (commercial fish), he takes a conscious risk. On the dorsal fins of a mini-shark there are spikes, in the back of which there are poisonous glands. Most wounds occur when the catch is removed from the net - a fisherman gets a severe burn, accompanied by prolonged pain. The poison of the katran is not lethal, but the wound will ache for several days.

A flat fish about the size of an average cucumber, which is tail-floating in the coast of Japan. The well-known image of a bug-eyed prickly ball takes puffer only in case of danger In general, such a funny camouflage for the human eye is the only way to protect this fish. Poison? Oh yeah, almost all the fugu's entrails are filled with tetrodoxin (the poison belongs to the nerve group, for a person there is a lethal dose of 1 mg). In Japan, fugu is a recognized delicacy, the cook requires a special license to prepare this dish, and the cooking itself consists of 30 rigorous steps. However, the fugu poison causes about 10 deaths each year (only registered).

Unlike zebra fish, the next representative of our list is very far from traditional ideas about beauty and aesthetics. You can meet poisonous toad fish in the coastal waters of South and Central America. The main "trump card" of this small (about 35 cm in length) creature is located in the dorsal fin, where several spikes with a dangerous substance lurked. In general, the prerequisites of being stung by a toad fish are not so much for a person, but if there is a painful contact, then you should not panic and drastically make a will. The sensations, of course, are extremely unpleasant, but still the poison of the toad fish does not apply to death for humans.

Fish-stone or wart also does not differ in special beauty, but easily disguises itself as sea stones (hence the name). The habitat of the creature is shallow water areas of the Indian and Pacific Oceans. Tourists from Europe have a chance to meet with a wart at the resorts of Egypt. The trouble with such a meeting is that, stepping on a stone with a "surprise", a person receives an injection of 12 "syringes" of the dorsal fin of the wart, which contain the strongest poison. Needless to say about pain, if a person is ready to tear off his own leg. It is important that the unlucky tourist is provided with immediate medical assistance, as the poison can cause death within 2 hours.

This flat fish, very much like a frying pan, is found in all tropical waters. The lion's share of life is carried by the bobtails at the bottom, and they tend to burrow into the sand in order to disguise, so an unwary tourist can step on the fish. The spike with poison is located at the slope in the tail (hence the name), but it uses its potential being only for defense purposes, and the poison does not represent a mortal danger. Nevertheless, one case is known when neither one nor the other statement worked. The victim was the famous naturalist Steve Irwin, who led another underwater shooting. Contrary to expectations, one of the stingrays was the first to deliver a smashing blow with a tail to Irwin’s chest, which caused instant death - the sting hit exactly in the heart.

This resident of the Black Sea and some parts of the Mediterranean in its usual state resembles a large sprat 30 cm long, painted with unusual patterns. Since the fish lives in shallow water and does not like to advertise their own presence (hiding or masking), by inattention a person may step on the whelp. In this case, the creature activates spines located in the dorsal fin and gills, from which poisonous glands enter the body of the “offender”. There comes a sharp burning pain, accompanied by swelling and cramps. In order to avoid serious consequences a person should be given first aid for 10 minutes.

In the tropical and subtropical waters of our planet scorpion lives - a fish with a unique appearance and ability to molt. In itself, the creature still hardly refers to the beautiful, but the motley coloring of the scorpions in thousands of options is simply amazing. In the same way as the poisonous arsenal of fish - around the perimeter of the calf are about 20 dangerous spikes. Color scorpion contributes to their easy disguise, so the fish can not notice and accidentally touch or step on it. Despite the impressive number of thorns, scorpion poison is not fatal, but symptoms such as pain shock, low blood pressure and numbness to the victim are provided for several days.

A small coral fish that lives in tropical waters, as well as off the coast of Japan, can pose a great danger to humans. Like most representatives of our list, the main weapon of inimicus (thorns with a poisonous substance) is hidden in the dorsal fins. The injection of this creature is justly equated to the bite of a viper, the main thing here is the help provided on time to the bather who has unsuccessfully entered the sea. By the way, our old acquaintances from Japan catch inimicus and use them as ... well, naturally, a delicacy. True cooking technology in this case is not so strict.

Finally, the most charming representative of our list. Indeed, the surgeon fish looks extremely cute and cute. However, this flat 40-centimeter beauty always carries with it poisonous spike-blades like a scalpel (hence the name). The fish is not predatory and uses its “ace in the hole” only when necessary. Such a need, by the way, can be the desire of a person to touch a cute fish. If unwanted contact has occurred, then the wound should be rinsed at the first opportunity with hot water or treated with a hairdryer - under the influence of temperature, the poison is destroyed and loses its detrimental properties.

Dangerous representatives of aquatic fauna

The poison is so strong that the dragonet is dangerous even for some time after death.
  5. Imicus. Translated from Latin means "enemy." Like many other venomous fishes, inimicus is dangerous for its dorsal fins, at the base of which there are poisonous glands.

  8. Shark katran. Translated from the Greek means "prickly." This name is not accidental; on the fins of such animals there are sharp thorns. And despite the fact that the katran has no poisonous glands, its injection is quite dangerous for humans. The reason for this is mucus, which can be covered with thorns. It develops many harmful bacteria that can cause infection.
  9. Scorpion. The end of the dorsal fin in such fish is a spike, at the base of which there are glands that produce poison. Bright coloring and outgrowths on the body make them almost invisible among the marine flora. The Black Sea marine ruff lives in the Black Sea - this is another name for scorpions. Their favorite places are shallow and coastal areas, so if you decide to wander along the coast, you should carefully look at your feet. Despite the fact that deaths from scorpion injections are rare, its poison can cause pain shock, swelling, and heart and lung disruption.
